 https://github.com/wildfly/wildfly-server-migration/releases

샘플 구성환경
-----------------------------------------------------------
Jboss 6.4 경로: /SW/jboss/jboss-eap-6.4
Jboss 7.2 경로: /SW/jboss/jboss-eap-7.2
-----------------------------------------------------------

메뉴얼 jboss-server-migration/docs/user-guide/index.html

1.jboss 7.2 설치

 /SW/jboss에 jboss-eap-7.2.5.zip 파일 업로드 (Jboss EAP 7.2에서 패치5가 적용된 파일)
 $ cd /SW/jboss
 $ unzip jboss-eap-7.2.5.zip

2.마이그레이션 툴 압축 해제 

/SW/jboss에 jboss-server-migration-1.7.0.Final.zip 파일 업로드
 $ unzip jboss-server-migration-1.7.0.Final.zip
 $ cd jboss-server-migration

3.마이그레이션 환경파일 수정

vi /SW/jboss/jboss-server-migration/configuration/environment.properties

----------------------------------------------------------------------------------------------------------------

4.마이그레이션 수행

5.jboss-eap 6.4의 실행/종료 스크립트 jboss-eap 7.2로 복사 후 환경에 맞게 수정

6.Jboss-eap 7.2 기동 및 서비스 점검

wokers..properties에 worker.xxx.fail_on_status=503 설정 추가

각 node에 설정하거나, templete에 설정

Wildfly, Jboss 연동 시 세션 중복처리가 가능한 상태로 설정해야 한다.

standalone-ha.xml

(변경 전)

(변경 후 - locking isolation, transaction mode 태그 삭제)

K8S 환경에서 prometheus 모니터링이 가능하도록 하려면 아래와 같이 리버스 프록시를 설정해야 한다.
http 포트 8080의 /metrics 호출 시 management 9990의 /metrics 로 전달
